Abstract : The capture-effect glide-slope system is explained by comparison with a standard null reference system, and the relative advantages of the glide-slope system are analyzed. A general exposition of monitor techniques leads to an analysis of capture-effect monitor problems; solutions for the particular capture-effect monitor problems are presented and logically justified. The recommended solution for the oncourse monitor is recognized as the monitordetector location is found on the antenna mast midway between the middle and bottom glide-slope antennas. An alternative solution for the course-width monitor is recognized as the monitor-detector location for the second null of the top-antenna resultant, where the middleand bottom-antenna resultants are in phase opposition at the 180-degree dephase point for middle and bottom antennas.
